You can claim confidentiality of substance components in mixtures through applying to use an alternative name at the HSE.

There are currently no fees for making this claim.

Rules on which substances can be claimed as confidential

Just like EU-CLP, you can only claim the use of an alternative chemical name for lower-hazard substances; and cannot make a claim for substances which hold a Workplace Exposure Limit.

Extract from HSE webpage:

You can request the use of an alternative chemical name for substances that:

  • have not been assigned a workplace exposure limit
  • are classified exclusively as one or more of the following hazard categories:
    • any of the hazard categories referred to in Part 2 of Annex I of the GB CLP Regulation (physical hazards)
    • Acute toxicity, Category 4
    • Skin corrosion/irritation, Category 2
    • Serious eye damage/eye irritation, Category 2
    • Specific target organ toxicity – Single exposure, Category 2 or 3
    • Specific target organ toxicity – Repeated exposure, Category 2
    • Hazardous to the aquatic environment – Chronic Category 3 or 4

WHAT TO DO IF YOU HOLD A PRE-CLP CONFIDENTIALITY CLAIM

CHIP confidentiality claims were respected under EU-CLP, so it is likely that they will still be honoured by the HSE.  However, we recommend you check with them to make sure.

WHAT TO DO IF YOU HOLD AN EU-CLP CONFIDENTIALITY CLAIM

As far as we are aware, this does not cover GB, so you should make a new claim.  However, as this is free of charge, it will only take your time.

CONFIDENTIAL MIXTURE COMPONENTS ON THE GB-SDS

You only need to identify these components by:

  • the alternative name as agreed with the regulators
  • the % w/w or % v/v (as applicable)
  • the hazard classification
